A Gain-scheduling Approach for Control of Dissolved Oxygen in Stirred Bioreactors

På svenska

Author

Summary, in English

This paper discusses control of dissolved oxygen in a bioreactor when the stirrer speed is used as control signal. During batch and fed-batch cultivations the operating conditions change significantly which causes tuning problems, especially when performance requirements are high. A linearized process model reveals that the variations in the oxygen dynamics are mainly due to changes in the volumetric oxygen transfer coefficient $K_La$.
